Kymber
Location when it matters.
Your location is yours. Kymber shares it only the moment you actually need it to — when you send it, accept a request, or raise an alarm. No always-on switch, no silent tracking, no trail of everywhere you've been.
Most location apps leave a switch flipped on, quietly broadcasting where you are until you remember to turn it off.
Kymber works the other way around. It never shares your location on its own. Your location goes out only when you choose to send it, accept a request from someone you trust, or raise an alarm.
The one thing that keeps running is a live share you started yourself — and it stays visible with a clear notification until you stop it.
From "I'm here safe" to "I need help now"
Some moments are light. Some are serious. Most apps handle one end or the other — Kymber is built for all of it.
Everyday sharing
Share live location on demand, for as long as you choose, and stop whenever you want. Request a quick check-in from a trusted contact — they stay in full control of their answer.
Meet up
Set a place and a time, see who's on their way, and optionally share live location as you head over. Coordinate the easy stuff without a group-chat scramble.
Letters, on your terms
Send a private letter or card to one trusted contact. Show your name or stay anonymous. Add your location or leave it off. Set it to expire — or to delete itself the moment it's read.
When seconds count
The SOS button alerts your emergency contacts instantly with an alarm that breaks through silent mode and Do Not Disturb, shares your live location, and puts 911 one tap away. Your exact coordinates stay on screen — so you can tell responders where you are even if you don't know yourself.
For the moments you can't speak
A Silent SOS you can send to a single person, with the alarm sound optional, plus a one-tap "I'm on my way" with optional live location. Reaching out — even quietly, even in a specific way — never feels out of reach.
Off grid in an instant
Flip your status to Unavailable and everything goes quiet — no one can request your location or reach you for sharing. Set a time window, add a reason if you like. The only thing that breaks through is a true SOS from an emergency contact.
A closer look
Every screen is built around one idea: nothing leaves your phone until you decide it should.
Home base
Share, meet up, or raise an alarm — all one tap from the start.
You decide
Someone asks; you choose. The share is one-way, and your location stays private until you say yes.
Quick send
One tap sends a warm note — with your location attached only if you want it to be.
Letters, on your terms
Anonymous, self-destructing, hidden from the lock screen, or set to expire. Every detail is yours.
Meet up
Pick a place and time, see who's coming, and share live location as you head over.
SOS, live
An active alert shares your location with your emergency contacts until help reaches you.
Your exact coordinates
Read them straight to a 911 dispatcher, or call with one tap — even if you don't know where you are.
Silent SOS
Reach one person quietly. The alarm is optional, and it never appears in your history.
Privacy you can see
Foreground-only location, no background tracking, and your address book is never read.
No trail behind you
Kymber keeps the points you choose to send — never a map of everywhere you've been.
Not everyone you trust belongs in an emergency
That's why Kymber keeps them apart — so the right people get the right kind of reach.
For when it's serious
The short list of people who can receive your SOS — a loud, breaks-through alarm with your live location, so help can come straight to you.
For everything else
The people you share with day to day — check-ins, meet-ups, letters, and on-demand location. Close, but not part of an alarm.
We keep only what it takes to work for you
Never sold, never tracked in the background. At any time you can delete individual letters, remove contacts, clear your history from view, or delete your account and everything tied to it.
No silent tracking
Kymber never shares your location on its own. The only thing that runs in the background is a live share you started — and it's always visible until you stop it.
Optional recovery
Off by default. Turn on Google sign-in recovery and your notes and settings survive a new phone — only if you choose to. Nothing is backed up unless you opt in.
Delete anything, anytime
Remove a letter, a contact, your history from view, or your whole account and everything tied to it — on your terms, from inside the app.
Frequently asked
Is Kymber free?
Yes — Kymber is free to download on Google Play, and the core safety features, including the SOS button, are always free. Some optional convenience features may be offered as a low-cost upgrade.
Does Kymber track my location in the background?
No. Kymber never shares your location on its own. It goes out only when you send it, accept a request from a trusted contact, or raise an alarm. The one thing that can run in the background is a live share you started yourself — and it always shows a visible notification until you stop it.
What devices does Kymber work on?
Kymber is available for Android phones through the Google Play Store.
How does the SOS button work?
Holding the SOS button instantly alerts your emergency contacts with an alarm that breaks through silent mode and Do Not Disturb, shares your live location so they can come to you, and puts 911 one tap away. Your exact coordinates stay on screen so you can give them to responders.
Can I send messages or notes through Kymber?
Yes. You can send a private letter or card to one trusted contact. Choose to show your name or stay anonymous, attach your location or leave it off, and set it to expire or delete itself the moment it's read.
Does Kymber read my phone's contacts?
No. Kymber never reads or uploads your address book — you add trusted contacts yourself. If you use the optional picker, Android hands Kymber only the single contact you tap.
What's the difference between emergency and trusted contacts?
Emergency contacts are the short list of people who can receive your SOS alarm. Trusted contacts are for everyday sharing — check-ins, meet-ups, and letters. Keeping them separate means the right people get the right kind of reach.
Do I need an account to use Kymber?
No. Kymber uses anonymous sign-in, so there's no password to create. You can optionally turn on Google sign-in backup so your notes and settings survive a new phone — only if you choose to.
Can I delete my data?
Yes, at any time. From the Privacy screen you can remove individual letters or contacts, clear your history from view, or permanently delete your account and everything tied to it.
